Oyster Shell Flour | Organic Calcium-Rich Soil Amendment for Healthy Plants

Enhance soil vitality with Oyster Shell Flour, an organic calcium source ideally suited for balancing soil pH and promoting robust plant growth.

What is Oyster Shell Flour?

Oyster shell flour is composed of 96% calcium carbonate and is enriched with numerous micronutrients. It provides a prolonged and steady release of nutrients while assisting in maintaining optimal pH levels in your soil, alleviating concerns about the need to adjust pH levels in your water source.

Oyster Shell Flour stands out as a premium calcium source that takes longer to decompose compared to other calcium options. Consequently, utilizing Oyster Shell Flour significantly mitigates the risk of nutrient lockout issues that may arise when used in conjunction with alternative calcium sources, which can be rapidly broken down within a few weeks in a sufficiently active rhizosphere.

Benefits of Oyster Shell Flour

Oyster Shell also contains chitin, which is advantageous for the plant's immune system.

Research indicates that Oyster Shell Flour can:

• Serve as a liming agent for the soil, facilitating pH buffering.

• Enhance soil tilth.

• Provide and help maintain favorable conditions for microbial activity.

• Stimulate enzyme activity.

• Increase Cation Exchange Capacity (CEC).

• Boost the plant's immune system.

How to Use Oyster Shell Flour

Oyster Shell Flour is intended to be used as a soil amendment. It is recommended to apply 1 cup per 30L of a base mix prepared in a 1:1:1 ratio.

Apply 2.5-5 lbs per 100 square feet, ensuring thorough mixing into the top 3 inches of garden soil during the spring or fall.
